Started in 1994, the Wolf Project has taken advantage of the visibility of Yellowstone's wolves to explore wolf population dynamics. Of particular interest is how wolves interact with prey and scavenger populations in the park. Smith hopes that Wolf Project research can help replace common misconceptions about wolves with factual information.
